JavaScript Message Boxes: alert (), confirm (), prompt ()
https://www.tutorialsteacher.com/javascript/display-popup-message-in-javascript
The alert() method in JavaScript displays an alert box with a specified message and an OK button. This method is used to ensure that information comes through to the user.
Example
alert("Hello! I am an alert box!!");
This will display a popup box with the message "Hello! I am an alert box!!" and an OK button.
Important Considerations
Modal Behavior: The alert box takes focus away from the current window, forcing the user to read the message. This prevents the user from accessing other parts of the page until the alert box is closed.
Usage: Use this method sparingly as it can be disruptive to the user experience.
Alternative Solutions
confirm(): Displays a dialog with OK and Cancel buttons.
prompt(): Displays a dialog with a text input field.
These alternatives can be used based on the requirement for user interaction.
